This document describes a proposed system to monitor the performance of electric vehicle batteries using Internet of Things (IoT) technology. The system would include sensors to measure battery cell voltage, current during charging and discharging, and other data. This data would be sent to a monitoring system controller and then transmitted to a battery monitoring software application via an IoT platform. The application would analyze the data and provide alerts to users about battery status via email or text message. It would allow users to access battery assessment reports for maintenance and troubleshooting. The proposed system is intended to help extend battery life and reduce maintenance costs by identifying performance issues early.
